FACILITIES AND PROCESSES AUTOMATION

METHOD OF STARTING ELECTRIC MOTOR There are several method of starting Induction Motor namely: ·      Direct on line starter commonly called DOL ·          Star Delta starter ·          Rotor resistance starter ·          Stator resistance starter ·          Forward and Reverse starter ·          Auto transformer starter ·          Frequency inverter starter .      Servo starter ( position/timing based) Before exploring the methods mentioned above, it is of higher importance to understand very well the makeup of an electric motor with emphasis on Three Phase Motor. There is virtually no process or packagining equipment that could operate in the industries without the need for motion transmissi...

No world could be described being completed thisdays without at least an application of control system. Control engineering trend is gaining more popularity in every sectors of any economy and all fields of endaveours helping us tackle the challenges of yesterday and improving the way we live and interact with our environment. Instrumentation, Automation and other areas of control engineering remains one of the bedrock of every Industrial and Domestic Processes. No single process in  industral environment would survive today tasks and process throughput without taking advantage of system automation. Let us examine together what makes this control ability possible both for Industrial and Domestic application. In real sense, automation is getting things done quickly in a predifined way with  or without human intervention. Some Systems are classified as Semi-automatic system which are designed to function with some human intervention while some are more or less an auto pilot ...
